Device and method for manufacturing double-laser shocked and forged titanium alloy lower leg fracture fixator

Abstract

The invention discloses a device for manufacturing a double-laser shocked and forged titanium alloy lower leg fracture fixator. The device comprises a workbench, a workpiece is placed on the top faceof the workbench, and a laser cladding system is arranged above the workpiece and generates a beam of continuous lasers. A heat effect is utilized for carrying out cladding forming on titanium alloy powder, a laser shocking system is arranged above the side of the workpiece, and shocking and forging are carried out on a cladding layer obtained through cladding forming. A powder conveying system isfurther arranged above the workpiece to continuously convey the titanium alloy powder to the top face of the shocked and forged cladding layer. The invention further discloses a manufacturing methodadopting the device for manufacturing the double-laser shocked and forged titanium alloy lower leg fracture fixator. Compared with the prior art, according to the technical scheme, the residual stress, deformation, structure defects and cracks and other adverse factors of the fixator can be eliminated or relieved better, true high-strength low-stress additional material manufacturing is achieved,and the technical problem that the fatigue life is short due to the residual stress can be avoided or reduced; and the fatigue life is prolonged, and high economic benefits and social effects are achieved.

Description

technical field [0001] The invention relates to the technical field of application of 3D printing medical devices, in particular to a device and method for manufacturing a titanium alloy calf fracture fixer for double laser impact forging. Background technique [0002] In recent years, with the aging of the global population and the increase in accidental injuries of the elderly, orthopedic diseases are becoming more diverse and complex, but traditional internal fixation implants are increasingly unable to meet the needs of individual treatment. [0003] Titanium alloy materials are widely used in biomedical devices due to their low density, high specific strength, and good mechanical properties, as well as their excellent corrosion resistance and excellent biocompatibility. With the rapid development of laser technology and intelligent manufacturing technology, 3D printing technology based on the principle of additive manufacturing has been widely used in many fields such a...
